Hey love your book and cards I been wondering what you think about using probes on difficult types of refrigerant should I clean them with Alcohol or just don’t do it

I was thinking can u just use a manual low loss fitting with 2 Shrader valve removal tools, instead of using 3 to keep your micron gauge clean ??

when connecting 【Angled Ball Valve】45 degree angle Manual Shut-off Valve fitting to the hose, should i be removing the "depressor" and gasket of the hose since there is already one at the end where the ball valve fitting connects to schrader valve?

My old 134a hose connectors won't fit on my 2018 Colorado A/C service ports. Did GM change their fittings.... Oh, nevermind. I see it now has R1234yf instead of R134a--$35 for 8 oz can.

Are most ports 1/4" in size? The manual of my Lennox says 5/8" of an inch. Thanks

7:10 WHERE CAN I GET THAT???? I can't seem to find a link in the video description.

I've searched and searched and I cant seem to find a chart to show refrigerant port thread and size. Does anybody know where to find this?

Can you please explain why when we have dirty evaporator the subcooling will be high and dirty condenser gives low superheat

@acservicetechchannel

4 жыл бұрын

If you have a dirty evap coil with a txv, subcooling will be higher but with a fixed orifice subcooling will be lower. A fixed orifice won't limit the superheat so you have more saturated refrigerant in the coil, therefore there is less in the outdoor unit to subcool. Thats why the subcooling is less with a fixed orifice. For a txv the amount of refrigerant needed to keep the superheat steady is less than normal due to the low heat load so there is more refrigerant in the outdoor unit, therefore more subcooling. Great question!

why do you only want automatic low loss fittings on the high side? Thanks for your videos, very helpful, will purchase your book

@scsclassics

Because you lose the most refrigerant from the liquid line when disconnecting using no fittings . You can use low loss fittings or ball valve shut offs on both high side and low side .Which ever you prefer.

In the manual for the MINI SPLIT I want it says to run the vaccum for 25 minutes. I don't understand how you can do that without the vacuum ending up too strong -ie the max vacuum power of the vacuum?.. The electric vac I'm looking at says it goes to "5Pa". I'm guessing that is way more than the -0.1MPa the manual says to do it to. This is so confusing... 5 Pascals = 0.000005 Mega Pascals (which I assume MPa refers to). -0.1 MPa = -100000 Pascals. I don't even know if higher numbers mean more or less vacuum any more.

I need the whole combo of fittings ,how can i order?

Hello. Which valve core depressor tool or any low loss do you recommend for 410a? These O rings are blowing like crazy! I have the yellow jacket and JB brand (JB last longer but can't find replacement O rings). I also have a twist style C&D (CD2060) which I attempted to use today and it was leaking right after what (cant think of exact name) screws onto the service port of the system. Thanks in advance.

Lee Byrd The best valve core removal tool is the Appion appiontools.com/mgavct/and there is also a mini-split version appiontools.com/mgavcr/. Both are available nationwide at United Refrigeration www.uri.com and Aireco www.aireco.com Remember to always use black HD hoses for vacuum & recovery and the bigger the hose, the faster the pull-down!

This person asked where is the link to the “valve depressor tool” mentioned in the video. The adapter fitting that screws on to 1/4” auto valve, depressing the valve, then your gauges screw on to the adapter. Someone responded with a link to “valve removal tool”. I can’t find the link either.

Can you pull a vacuum on a system with low loss fittings?

@acservicetechchannel

I would not do that due to leaking the vacuum through them or obstructing the vacuum, thanks!

I don’t see the angle stop that you turn to open and close listed.

When the rest of the world went from R22 to R410A, they decided to differentiate their service valves so that techs wouldn’t add R22 to a 410A system. Being the good ol’ USA and doing our own thing (ex. Not going metric), we stayed with the 1/4” valves. NRP is going to introduce mini-split hoses and will be available @ UR locations nationwide by fall 2020.

I retired from HVAC a few years now. I have an old R22 pressure gauge, and I installed a mini system for my garage, but my gauge end wont fit the service valve of the 410A system. Is there an adapter to fit the older gauge? I'll be using the high side of the older gauge on the low side of the system . I don't want to have to spend money for new gauges just for the one time use.

You want a 5/16 adapter

Why is it so hard to find a 1/4” female to 1/2” adapter for vacuum’s that only have 1/2” fitting?? I bought R12 to 134R fitting but the threads are backwards and pissing me off to find a right hand threads in that size!!
